Title: Improvements in or appertaining to Electric Motor Drives for Planing Machines and the like.
Inventor: HAGGAS FRED THORNLEY
IPC: B23Q15/007
Filed: 1918-10-16
Abstract: 136,589. Haggas, F. T., and Haggas, W. Oct. 16, 1918. Systems controlling reciprocating motions of planers.-A planing or like reciprocating machine is driven by an electric motor rotating in one direction only and having an adjustable shunt-field resistance which is cut into circuit for one stroke by a switch operated by the belt-shifting mechanism, and cut out for the other stroke by the same switch. The table c of the machine shown has two driving-belts a, b, the latter belt being used for the high-speed idle stroke, which is made with the field resistance cut out. For the working stroke, the field resistance is in circuit, and the motor f<1> rotates at a high speed, but acts through additional gearing so that the table moves at a slower speed than during the idle stroke. The lever e for changing the gears is operated from the table as described in Specification 117,315, [Class 83 (iii), Metals, Cutting], and the lever also operates the switch controlling the insertion of the field resistance. The connexions are shown in Fig. 3. The first movement of the starting-lever on its pivot h<4> bridges the contacts h<1>, h<2> to complete the circuit of the actuating-coils n, n<1> of the main switch. This switch then completes the motor circuit, and the rheostat arm may be moved to cut out resistance. A resistance 12 is connected in series with the coils n, n<1> by this movement, so that if the supply fails the rheostat arm must be returned' to the maximum resistance position to close the main switch. The arm of the field resistance k may be adjusted by hand to give any desired speed for the cutting stroke, but the switch g<3> is closed at the end of the stroke and keeps the resistance short-circuited during the return stroke. An indicator k<2> is provided in connexion with the field rheostat.

Title: Method of producing polyurethane elastomer
IPC: D01F6/70
Filed: 1966-04-18
Abstract: A polyurethane elastomer is prepared by reacting at a temperature of 170 DEG  to 250 DEG  C. an essentially anhydrous mixture of (1) an essentially linear polymeric organic compound having terminal hydroxyl groups and a M.W. of 500 to 5000; (2) a saturated aliphatic glycol containing 2 to 12 carbon atoms; and (3) an organic diisocyanate the molar ratio of (2):(1) being in the range of 1.6:1 to 3.0:1 and the amount of diisocyanate in the mixture being in a 2 to 8% molar excess of the combined amounts of glycol and polymeric hydroxyl group containing compound. Suitable polymeric organic compounds having terminal hydroxyl groups are polyesters and polyethers.  Exemplified polyesters are those prepared from a mixture of ethylene glycol, 1,4-butane diol and adipic acid, a mixture of 2,2-dimethylpropanediol, 1,6-hexanediol and adipic acid and polycaprolactone whilst the exemplified polyether is poly(tetramethylene glycol).  In the case of the polyesters a small amount of a polyol such as trimethylolpropane, trimethylol ethane and pentaerythritol may be incorporated into the polyester.  A similar polyol may also be incorporated into the aliphatic glycol (2).  The preferred aliphatic glycols (2) are 1,4-butanediol and 1,6-hexanediol.  Many diisocyanates are listed those preferred being aromatic diisocyanates especially 4,41-diphenylmethane diisocyanate. The resulting polyurethane melt may be spun to form filaments or shaped into other articles both of which may be subjected to a heat treatment at 50 DEG  C. to 250 DEG  C.

Title: Method of and means for making hem-stitched seams and the like
IPC: D05B21/00
Filed: 1932-06-15
Abstract: 383,906. Sewing &c. SCHEIBEL, K. G., 18, Max Klingerstrasse, BOHMANN, A. A., 75, Dohnaerstrasse, and WURKER GES., 16, Pirnaische Strasse, all in Dresden, Germany. June 15, 1932, No. 16945. [Class 112.] Hem-stitching machines ; stitches and seams.- Each stitch hole of a hem stitch is connected to each adjacent stitch hole of each series of stitch holes by a plurality of threads in one pattern repeat. Enlarged holes are made by a coarse needle and the holes are bound together a number of times by stitches in triangular, Fig. 5, quadrangular or other patterns by a machine having a needle which vibrates either transversely to or in the direction of the line of seam, or which simply reciprocates, in conjunction with a feed device which vibrates either in the direction of or transversely to the line of seam, or both. The stitch may be made by an attachment secured to the presserbar 1, Figs. 13 and 14, of a domestic sewing machine having a reciprocating needle-bar 6 which imparts step-by-step rotary movement to a shaft 11 through a pawl and ratchet mechanism driven from the needle-bar. The shaft 11 carries two cams I, II which actuate, alternately or simultaneously, a feed device in the form of a frame in two directions at rightangles. If desired these movements may be obtained from a single compounded cam, or one cam may actuate the needle bar and the other mav actuate the feed device. These cams I, II may be exchangeable, to permit the stitch to be varied. The work is only moved forward bodily after completion of each repeat, either by a separate feed device or by the same feeder. In this latter case, a lift lever 42 controlled by a cam 41 presser on the work and lifts the whole device bodily a little so that the feed device passes idly over the work. A piercer which operates in advance of the needle and which may be mounted on the lift lever 42 or on a vertically reciprocating push-rod may be employed to form holes in the fabric. Alternatively, one piercer may pierce the fabric and a second and longer piercer may enlarge the hole so formed. The stitches on the rear side of a turned-up seam composed of hem stitches according to the invention may be cut out, and, if desired, the seam can be cut along the edge to produce articles having pointed edges. German Specifications 484,439 and 541,661 are referred to.
